<p>A hybrid electrochemical water softening desalination system softens water by both electrodialytical and non-electrodialytical means before desalinating the softened water in a primary desalination subsystem. The concentrate produced as byproduct from the desalination is provided to a concentrate channel of the electrodialysis device employed, and the electrodialysis device extracts multivalent ions from the water to the concentrate channel. In some embodiments the electrodialysis device provides softened water directly to the primary desalination subsystem. In other embodiments the electrodialysis device provides electrodialytically softened water to a non-electrodialytical softening subsystem for further softening, before the softened water is supplied to the primary desalination subsystem. The arrangement integrates the concentrate disposal line of the primary desalination subsystem with the functioning of the electrodialysis device.</p> |
